Dr. Rafik Hadfi is an assistant professor in the Department of Social Informatics at Kyoto University. He received his Ph.D. from Nagoya Institute of Technology in 2015 and has worked in Japan and Australia before joining Kyoto University in 2020. His research interests lie in the design, development, and application of multi-agent systems for social simulation and collective decision making. He is currently using conversational AI to study deliberation, polarization, and fairness in social networks. Rafik is also working on multi-agent automated negotiation with the focus on social domains. Rafik served as a program committee member of leading AI conferences such as IJCAI, AAMAS, SNPD, and IEEE ICA and a reviewer for Group Decision and Negotiation; Artificial Intelligence Review; Neural Computation; Advanced Computational Intelligence and Intelligent Informatics; and Networked and Distributed Computing. Rafik has been the publication chair, the workshops chair, the tutorials chair, the volunteers chair, and the web chair for international AI conferences such as IJCAI, PRICAI, PRIMA, and IEEE ICA. In 2022, he will serve as the program chair of IEEE ICA. Rafik received the annual conference award from Japan Society for Artificial Intelligence (2020), IBM Award of Scientific Excellence (2020), Best Paper Award from Information Processing Society of Japan (2016), IEEE Young Researcher Award (2014), AAAI Student Scholarship Award (2014), and Best Presentation Award at the International Workshop on Agent Complex Automated Negotiations (2011).

Dr. Reyhan Aydöan is an assistant professor at Ozyegin University, Istanbul, and at the same time affiliated as a guest researcher in the Interactive Intelligence Group at the Delft University of Technology, the Netherlands. As a guest researcher, she visited the Center of Collective Intelligence at MIT in 2013, the Intelligence Systems Group at the Norwegian University of Science and Technology in 2015, and theFrontier Research Institute for Information Science at Nagoya Institute of Technology in 2017. Her research focuses on the modeling, development, and analysis of agent technologies that integrate different aspects of intelligence such as reasoning, decision making, and learning. She applies artificial intelligence techniques such as machine learning and semantic reasoning in designing and developing agent-based decision support systems, particularly negotiation support systems and automated negotiation tools. Dr. Aydöan is one of the main organizers of the International Automated Negotiating Agents Competition (ANAC). She co-organized the following workshops: Conflict Resolution in Decision Making Workshop (COREDEMA) and International Workshop on Agent-based Complex Automated Negotiations (ACAN). She is serving as a program committee member in reputable conferences such as AAAI, AAMAS, IJCAI, and ECAI. She served as a guest editor for the Special Issue on Artificial IntelligenceTechniques for Conflict Resolution in Group Decision and Negotiation. Furthermore, she co-organized the 24th International Conference on Principles and Practice of Multi-agent Systems in 2022.
